This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X150-30SB, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X150-30SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X150-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30SB
This is a double acting compact cylinder with an adjustable extend stroke, built to the DIN-standard ACPJ format: a hard-anodized aluminium body, an S45C hard-chrome piston rod and a fixed TPU bumper at each end. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (rising to 79.2 N push at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. The 150 mm stroke is longer than the 50 mm standard maximum for this bore, so it is a made-to-order build.
The -30 code gives a 30 mm adjustment window: an external stop screw trims the extend stroke anywhere between 120 and 150 mm on site, so one cylinder covers several jig positions. Because the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight guards and gantries. As a planning rule, budget about 34 N (roughly 3 kg vertical lift with a 2:1 margin) of real work at 0.5 MPa rather than the full rating. Note this model is discontinued: the current-production replacement is ACEJ12X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-30SB (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30SB Is Used
Micro-part ejector on a small press jig
The 56.5 N push at 0.5 MPa is enough to strip light aluminium or plastic parts from a shallow die cavity, and the 120-150 mm adjustable range lets one cylinder serve several die heights.
Position-verified sliding gate on a test bench
With the -S magnet fitted, CMSE or DMSE switches confirm the fully extended and retracted positions of a small instrument cover, running at 30-500 mm/s.
Light pick-down probe in an electronics fixture
The stop screw set to 130 mm gives a repeatable short press for seating connectors, while the compact body fits inside a crowded PCB handling gantry.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30SB with the ACEJ12X150-30SB
Size by force first: if 56.5 N push at 0.5 MPa is marginal for your tooling, step up to the 16 mm bore (100.5 N push) or the 20 mm bore (157.1 N push) in the same compact family. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod still drifts, so add a separate brake or valve if you need position holding. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted directly; the male rod thread (B code) suits external knuckles. Order ACEJ12X150 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-30SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 12 mm bore uses an M5x0.8 port and a 6 mm male-threaded rod. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, on air filtered to 40 um. The 150 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
The -30 code means an external stop screw shortens the 150 mm extend stroke by up to 30 mm, giving a usable range of 120-150 mm; it cannot lengthen the stroke past the ordered value. The stop is a mechanical end stop only - it never holds a load if air is lost. Fixed TPU bumpers decelerate the piston at both ends. This ACPJ is discontinued; the current-production drop-in is ACEJ12X150 in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before you swap.
